Application filed December 12, 1901. Serial No. 85,581. (No model.)

To ctZZ whom it 777/(bjL/007Z067'7b: an opening within the partition 16, passing Be it known that I, ALBERT E. OAUGHEY, transversely across the housing. Secured residing at 2541 Davenport street, Omaha. in within the compartment formed by means of the county of Douglas and State of Nebraska, the end a and the partition 16 are the two have invented certain useful Improvements insulating-blocks f, positioned one above the in Railroad Signals and Alarms; and I do other. and to the upper barfis secured aninhereby declare that the following is a full, verted-J-shaped spring D, while to the lower clear, and exact description of the invention, blockfis secured a smaller J-shaped spring such as will enable others skilled in the art to E, the end of these spring-terminals being adzo which itappertains to make and use the same, jacent one another, as shown in Fig. 1. Exreference being had to the accompanying tending from the spring D is a suitable trackdrawings, which form a part of this specifiwire W, while extending from the remaining cation. spring E is a second track-wire V, as shown.

This invention relates to a new and novel Positioned adjacent the spring-lever H is a 15 track mechanism to be used in connection stop 12, provided with the extension 10,

with a suitable alarm. against which the lever H works.

The aim of my invention is to provide a Whentheinstrumentalitieshavebeen propmechanisu'l adapted to be placed adjacent the erly arranged, the operation of my device will track, to be operated by the wheels of the vebe as follows: Should a train approach from 20 hicles passing over the same to form an electhe direction as indicated by the arrow :1; in

To this the electric terminals D and E with a sliding pin is secured the spring-actuated lever H, movement, which would have a tendency to which above is provided with the enlarged keep these contact-points bright. The end head 16, forming a seating, within which is of the push-bar 15 is provided with suitable held the upper end of the coil-spring F, pressinsulating material 0, as shown. As soon as 5 ing below upon the bottom b of the housing these terminals D and E are drawn together A. Pivotally secured to this spring-actuated the track-wires will be connected to operate lever I-I, approximately midway, by means of any suitable electric gong used in connection the screw 9, is the toggle-bar K, which at its with my device. upper end, by means of the screw 8, is se- Any electric signal which is operated when 40 cured to the striker end 0, as shown.
